For symptomatic bradycardia, the usual dosage is 0.5 to 1 mg IV push; this may be repeated every 3 to 5 minutes, up to a total dose of 3 mg (maximum 0.04 mg/kg). [ 23 ] Atropine is also useful in treating second-degree heart block Mobitz type 1 (Wenckebach block) , and also third-degree heart block with a high Purkinje or AV-nodal escape rhythm .
The 2005 Joint European Resuscitation and Resuscitation Council (UK) guidelines [17] state that atropine is the first-line treatment especially if there were any adverse signs, namely: 1) heart rate < 40 bpm, 2) systolic blood pressure < 100 mm Hg, 3) signs of heart failure, and 4) ventricular arrhythmias requiring suppression. If these fail to ...
The main contraindication for ipratropium in any form is hypersensitivity to atropine and related substances. [20] [21]Conditions such as narrow-angle glaucoma, prostatic hyperplasia, or bladder neck obstruction are not necessarily contraindicators, but should be taken into account, particularly if the patient is receiving an anticholinergic by another route.
However, scopolamine has greater effects on the central nervous system (CNS) than atropine due to its ability to cross the blood–brain barrier. [4] At higher-than-therapeutic doses, atropine and scopolamine cause CNS depression characterized by amnesia, fatigue, and reduction in rapid eye movement sleep.
At some point before surgery a health care provider conducts a preoperative assessment to verify that a person is fit and ready for the surgery. [1] [2] For surgeries in which a person receives either general or local anesthesia, this assessment may be done either by a doctor or a nurse trained to do the assessment. [2]
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes). This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
ET absorption of medications is poor, and optimal ET drug dosings are unknown. IO administration is becoming more common in civilian and military pre-hospital emergency medical services (EMS) systems globally. [11] Intraosseous access has roughly the same absorption rate as IV access, and allows for fluid resuscitation.
